摘　　要：以获取某校景观石的三维激光扫描点云为实例,解决在三维激光扫描过程中由于环境因素、信号干扰等产生点云噪声的问题,并对点云拼接、点云滤波、模型重建等方面进行探讨;对基于点云数据建立的模型进行影像纹理映射的研究,并对在纹理映射中出现的各种问题进行探讨与解决,总结出一种从点云数据的采集到建立具有真实感的三维模型建模方法。使用RiSCAN pro,Geomagic Stdio 11逆向工程软件以及3ds Max软件进行处理和解决,最终实现了复杂表面物体的三维模型重建。实验结果表明,文中方法能够快速准确地处理三维激光扫描仪所获取的点云数据,对实现复杂表面物体快速三维可视化模型重建具有一定实用性。T his paper ,taking a school landscape stone 3D laser scanning point cloud as an example ,aims to solve the 3D laser scanning process due to environmental factors and signal interference ,and discusses the point clouds noise problems , point clouds registration , point cloud filtering aspect , and model reconstruction .Based on the model established by point cloud data for image texture mapping study ,it explores and solves the emerging problems in the texture mapping and sums up a collection point cloud data from a 3D model to a realistic modeling method .RiSCAN Pro Geomagic Studio 11 reverse engineering software and 3ds Max software are used to handle and resolve to ultimately realize the 3D surface reconstruction of complex objects .Experimental results show that this method can quickly and accurately process point cloud data to obtain a 3D laser scanning .T he realization of complex 3D surface of the object＆#39;s rapid visualization model has a certain practicality on reconstruction .
